A Comparison of Standard Grout Mix to Self-Consolidating Grout Mix is a well-researched Engineering Thesis/Dissertation topic, it is to be used as a guide or framework for your Academic Research.
Masonry is a major structural material for low rise buildings, however, the design of masonry buildings is rarely taught as a formal course at most universities. As part of the educational experience and to become familiar with the specifications and testing procedures for grouped masonry, a student-run experiment on varying the water to cement ratio of masonry grout was conducted.
The purpose is to report on the effects of changing the water-to-cement (W/C) ratios in a standard grout mix. The typical W/C ratio is approximately 0.80:1.00. In order to show the effects of increasing water in a grout mix, a second grout mix was investigated – a 1.00:1.00 W/C ratio. The two W/C ratios investigated were a 0.74:1.00 and a 1.00:1.00 W/C ratio.
Students prepared and tested the 0.74:1.00 grout mix per the standard of the American Society of Testing and Materials (ASTM) Standard C476 Table 01: Conventional Grout Proportions by Volume, and the ASTM Standard C1019: Standard Test Method for Sampling and Testing Grout.
In order to achieve the purpose of educating the students, while providing valid ASTM comparison tests, all necessary steps of the process are included in this report. In bullet form the steps are
Derivation of Standard Grout Mix Design
Slump test for 0.74:1.00 Standard Grout Mix
Slump flow test for 1.00:1.00 Grout Mix
Cutting Prisms out of the CMU blocks & Final Curing Stages
Capping and Testing of Prisms
What we learned
The introduction section will discuss the derivation of the standard grout mix design and the mix process. The background section discusses how adding excess water changes the characteristics of a standard grout to a self-consolidating grout.
The background section also describes the different types of prisms per American Standard Testing Method (ASTM) C1314. The majority of the report is in the Experimental sections, with the final section containing results from the testing and lessons learned.
